PLEASE HELP ME OUT.

[lords007]

I purchased a second hand Toyota Vitz 2011 (KSP-1KR) and it was in good condition just 30000 KM driven. This is for the first time i purchased a vitz.

Problems are;

1. Knlocking sound coming from engine when i press the accleration padle.

2. Now its almost 40000 KM driven but car start consuming engine. I am using Toyota Patron A+ engine oil. i dont remember the oil which was used before. but now after three oil change still engine is consuming oil, i got to toyota but they say that its normal, each and every thing is f9. Rest vehicle is good. first oil change was made at 1000 KM, 2nd was on 3000 and the third is also on 3000, although the mechanics were saying that this oil has a running of 6000 KM.

3. i also change the tyres and used slightly bigger i.e. 185/65/R15.

4. more over can i use high octane in it.

As i m new here need guidence and positive comments. and recommendations.

Regards,

DAVID
